CHARLES JENKINS, OF BOSTON, MASSACHUSETTS.

MACHINE FOR FORMING BRIQUETS.

SPECIFICATION forming part of Letters Patent No. 762,906, dated June 21, 1904:.

Application filed August 21, 1903.

To all whom itmzry concern:

Be it known that 1, CHARLES D. JENKINS, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Forming Briquets, of which the following is a specification.

This invention relates to machines for forming ,briquets of peat, soft coal, or similar maof a machine into which material maybe fed, subjected to a great pressure, and delivered therefrom in briquets of uniform shape.

It consists in certain novel features in construction and arrangement of parts,which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents a sectional plan of a machine embodying this in, vention, the cutting plane being on line 1 1 on Fig. 2. Fig. 2 represents a sectional plan of the same, the cutting plane being on line 2 2 on Fig. 1. Fig. 3 represents an enlarged sectional elevation of the same, the cutting plane being on line 3 3 on Fig. 2. Figs. 4 and 5 are respectively a transverse section and a vertical longitudinal section of the easing for the screw conveyer; and Fig. 6 represents a vertical section of a bed-plate, showing in elevation a side plate with its pivoted cam.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 is a main frame of the machine, having secured thereto a casing 11, in the conical chamber 12 of which is mounted a screw conveyer 13, to which the material to be used is fed through an inlet 14. .The inlet 14 enters the conical chamber 12 near the outer end of the screw and at such an angle as to feed the material directly toward the cdgeof its blade, so that in the revolution of the screw conveyer 13 its cutting-blade will be forcing its way into thematerial being fed thereto. v,

The spindle 15 of the screw-conveyor 13 is mounted in a bearing 16 and is provided with Serial No. 170,307. (No model.)

the chamber 12 and to the top of the frame 10 are secured two upright plates 21, provided with bearings for a shaft 22, which is provided with a gear 23, meshing with a pin-'- ion 24 on the shaft 25, which is driven at any desired speed by the pulley 26.

Between the plates 21 and upon the shaft 22 are securely mounted two wheels 27, each provided with a series of radial arms 28 and a central strengthening-rib 29, extending nearly to the end of said arms 28-.- These arms 28 of the two wheels 27 are in the same plane and coact with the side plates 21 to form a plurality of chambers open at their ends and in which are mounted a series of movable bottoms 30, provided with fingers- 31, which straddle the ribs 29 of the wheels 27 for the purpose of directing the movement of said bottoms 30. 7

Each of the bottoms 30 is provided with lugs 32, which project into a recessin said plates 21 and are acted upon by the cam-surface 33 to control the movement of the bottoms 30, said bottoms 30 being kept at a uniform distance from the shaft 22 until they reach a convenient point, when the lugs 32 are operated upon by the throw 3 1 to move the bottoms to the extreme ends of the armsthe arm into different positions to vary the movement of the movable bottoms 30, and

thereby vary the amount of compression-given to the briquets in the chambers in the periphery ,of the wheels 27. Between theside plates 21 is secured by suitable bolts abedplate 39, the upper surface of which conforms to the periphery of the wheels 27, with which 41 to a heating-chamber L2, secured to the under side of the frame beneath the revoluble wheels 27. This chamber 42 is connected by a pipe 4L3 to another heating-chamber 44,

formed in the casing 11. This chamber is provided with an inlet 45, by which steam or other heat may be introduced to said chambers, circulating through the series of heatingchambers, causing the material being fed to the wheels 27 and being operated upon to be thoroughly heated, thereby facilitating the operation of the machine, and discharging the compressed peat in a thoroughly dried and baked form free from moisture.

The chamber a4: is provided with a series of partitions 46, thereby forming a series of tortuous passages from the inlet 45 to the outlet 43, thus causing the heat to pass over the entire surface of the casing 11, thoroughly heating all parts thereof.

Each of the movable bottoms 30 is provided with a central rib 47 on its working surface, which is adapted to make a depression in the briquets compressed in each of said peripheral chambers, this depression acting as a ready means for dividing the briquets, as is often desired for some uses.

The operation of the machine is as follows: The material to be used is fed into the machine through the inlet 14 to the screw conveyer 13, which revolves toward the same, thereby cutting into the material being fed thereto and forcing the same through the conical chamber 12 to the inlet between the side plates 21 and into the chambers in the periphery of the Wheels 27, which, revolving in the direction of the arrow, Fig. 2, compresses the material therein by means of the action-of the cam 33 upon the lugs 32, secured to the movable bottoms 30.

The screw conveyer 13 is arranged to deliver a greater quantity of material than the wheels 27 can remove without compression of the same, and as a consequence the material is forced into the chamber under a greater pressure and is delivered at a predetermined point in a compact mass of uniform size.- Both of the driving-shafts are driven from the counter-shafts at such a speed as will produce the best results.

It is believed that from the foregoing the invention will be thoroughly understood without further description.
